S1D13705 power consumption is affected by many system design variables.
• Input clock frequency (CLKI): the CLKI frequency and the internal clock divide register deter-
• CPU interface: the S1D13705 current consumption depends on the BUSCLK frequency, data
• V
• Display mode: the resolution, panel type, and color depth affect power consumption. The higher

There are two power save modes in the S1D13705: Software and Hardware Power Save. The power
consumption of these modes is affected by various system design variables.
